For example talc is very soft.
Talc is the softest mineral; his hardness is 1 on the Mohs scale.
the mineral that has a hardness of 7 is "Quarts
Mineral hardness is measured by how resistant one mineral is to being rubbed against another. If the mineral displays clear abrasion then it has low hardness whereas if it displays little abrasion it is a hard mineral.
The unknown mineral has a hardness greater than that of apatite (which has a hardness of 5 on the Mohs scale) since it can scratch it. However, it has a hardness less than corundum (which has a hardness of 9) since it can be scratched by it. Therefore, we can conclude that the hardness of the unknown mineral is between 5 and 9 on the Mohs scale.
The Mohs hardness of serpentine is 2,5-3; it a soft mineral. Not scrached by a graphite pen; scratched by fingernail, copper etc.
The mineral that has a similar hardness to a fingernail is gypsum. Gypsum has a Mohs hardness of 2, which makes it soft enough to be scratched by a fingernail.
Biotite mica has a Mohs hardness of 2.5-3.0.
Wulfenite has a mineral hardness of 3-3.5 on the Mohs scale, which means it is relatively soft and can be easily scratched by harder materials.
Talc is the softest mineral; his hardness is 1 on the Mohs scale.
No, sulfur is not a soft substance. It is a solid mineral that can vary in hardness depending on its form, but generally, it is considered to have a moderate hardness level.
Halite has a hardness of 2-2.5 on the Mohs scale of mineral hardness. This means it is relatively soft and can be easily scratched with a fingernail or a copper coin.
Galena has a hardness of about 2.5 on the Mohs scale of mineral hardness. This means that it is relatively soft and can be easily scratched with a fingernail or a metal object.
No a mineral with a low number CAN NOT scratch a mineral with a high number. For example : Mineral Talc is 1 on the MOH Hardness Table and a soft mineral. The Diamond is a 10 on the MOH Hardness Table and is the hardest mineral.
It's about 1.5-2 on Mohs scale of mineral hardness.
The mineral with hardness 3 will get scratched.
To find the hardness of a mineral, you would look at its ability to resist scratching by harder substances. This is typically measured using the Mohs scale of mineral hardness, which ranges from 1 (very soft) to 10 (very hard).
Gold ranges from 2.5-3.0 on the Mohs scale of mineral hardness.
